Antifreeze and coolant: protect your engine in all seasons

Antifreeze, or engine coolant, prevents freezing, overheating and corrosion. Choosing the correct coolant type and following replacement intervals preserves engine health and prevents costly repairs. This overview helps you understand specifications and safe handling.

How to choose and use coolant

Refer to your vehicle handbook for the recommended coolant specification. Coolants vary by formulation—ethylene glycol or propylene glycol bases and different additive packages for corrosion protection. Mixing types can harm the cooling system, so use the specified product. Check concentrate versus pre-mixed versions and follow dilution guidance. Regular coolant checks and timely flushes remove deposits and maintain heat transfer efficiency.

Practical tips and safety

• Specification match: always use the coolant type approved for your engine to protect seals and alloys.
• Mixing and disposal: dispose of used coolant responsibly—do not mix incompatible types.
• Performance signs: monitor temperature gauges, leaks and coolant colour for early faults.
• Radiator additives: use only manufacturer-approved products when needed.
• Buying advice: buy from reputable sources and check for clearance or bulk deals for seasonal maintenance.

Store coolant safely away from children and pets, and follow instructions when topping up or changing. Proper coolant maintenance extends engine life and ensures reliable performance year-round.
